Answer:
[tex]\huge\boxed{\sf x = 65\°}[/tex]
Step-by-step explanation:
Firstly finding y:
We know that: "The measure of the exterior angle is equal to the non-adjacent interior angles."
So,
y = 60 + 55
y = 115°
Since:
y + x = 180 (Angles on a straight line add up to 180 degrees)
115 + x = 180
subtract 115 to both sides
x = 180 - 115
x = 65°

Answer:
x = 65
y = 115
Step-by-step explanation:
let the unknown angle be z
so , 60+55+angle z = 180 { angle sum property }
=> 115 + angle z = 180
=> angle z = 180 - 115
=> angle z = 65
now angle z is equal to angle x { because of they are vertically opposite angles }
x = 65
now, for angle y
angle y + angle x = 180 { because they are linear pair }
65+y = 180
y = 180-65
=> y = 115
